Short description of error
The bottom bar states that pressing ^ will enable snapping, but it seems it does nothing.

Exact steps for others to reproduce the error

1. Create a new default file;
2. Go to the compositor;
3. Enable nodes;
4. Add a viewer node (this allows you to resize and test different sizes for the Corner Pin Gizmo);
5. Add a Corner Pin node;
6. Edit the Corner Pin widget and try to snap.
